SMS Consent Process

This page documents how VoiceCraft AI agents obtain consent from callers before sending SMS messages on behalf of businesses. It is intended to provide transparent, publicly verifiable evidence of the opt-in process for regulatory review, including by wireless carriers and The Campaign Registry (TCR) as part of A2P 10DLC campaign registration.

VoiceCraft operates an AI-powered phone receptionist for small businesses. When a caller books an appointment, requests information, or completes another action that would be useful to confirm via text, the AI agent may offer to send an SMS. No message is sent without explicit verbal confirmation from the caller.

This consent process applies to all SMS sent under the VoiceCraft SMS Notification Program, as described in our Terms of Service and Privacy Policy.

Consent is collected verbally during an inbound phone call. The process follows these steps:

1. A customer calls the business's VoiceCraft phone number. The call is answered by an AI voice agent.
2. The agent handles the caller's request, for example, booking an appointment or providing business information.
3. After completing the request, when sending a confirmation or summary would be useful, the agent presents an explicit opt-in offer. The agent reads a disclosure that includes the message type, that message and data rates may apply, and how to opt out.
4. The caller must respond affirmatively (say “yes,” “sure,” “okay,” or equivalent) to consent. Silence, hesitation, or any response that does not clearly indicate agreement is treated as a non-consent and no SMS is sent.
5. Only after receiving a clear affirmative response does the platform queue the outbound SMS.

In addition to verbal consent during a call, callers who have previously opted out may re-subscribe at any time by texting START or YESto the business's number. This is the only other opt-in path supported.

The following is the exact language the AI agent uses when offering to send an SMS. The wording may be adapted slightly based on the context of the call, but the required disclosure elements are always present.

All three script variants contain the required disclosures: the sender's identity (business name), that message and data rates may apply, and the opt-out instruction (STOP). The agent waits for an explicit “yes” before proceeding.

In addition to the verbal consent process, VoiceCraft enforces the following technical controls to prevent unsolicited messaging:

Caller ID gating

The destination phone number for any outbound SMS is always the number that originated the inbound call, captured from the SIP signaling layer (caller ID). The platform rejects any attempt to send SMS to a number that did not originate the current call session. This prevents agents from texting third-party numbers.

Consent state enforcement

The platform tracks opt-out status per phone number per business. Once a number has replied STOP, it is added to a suppression list for that business's number. All outbound SMS requests are checked against the suppression list before delivery. Messages to suppressed numbers are dropped silently.

Keyword handling

The platform processes standard carrier keywords automatically:

• STOP, QUIT, CANCEL, UNSUBSCRIBE, END: Immediately adds the number to the suppression list and sends a single opt-out confirmation message. No further messages are sent.
• START, YES: Removes the number from the suppression list and sends a re-subscription confirmation.
• HELP, INFO: Sends the help message with support contact information.

No unsolicited outbound

VoiceCraft does not initiate outbound SMS to numbers that have not first called the business's VoiceCraft number. The platform has no mechanism to send cold or marketing SMS to numbers sourced from external lists.

All SMS sent through VoiceCraft are transactional in nature. The following message types and samples represent the complete set of message categories used:

Every message identifies the sending business by name and includes opt-out instructions. No promotional, marketing, or advertising content is sent.

Message frequency varies. A customer who books an appointment typically receives 1 to 4 messages over the course of their appointment cycle:

• 1 booking confirmation at the time of scheduling
• 1 reminder message 24 hours before the appointment
• Up to 2 additional messages if the customer initiates a follow-up or rescheduling via SMS reply

Customers who do not book appointments but request information during a call will receive 1 message containing that information.

Message and data rates may apply.Standard messaging and data rates from the customer's wireless carrier may apply to all messages sent and received. VoiceCraft does not charge customers for receiving SMS messages.

To stop receiving SMS messages from any business using VoiceCraft, reply STOP to any message at any time.

The following opt-out keywords are all recognized:

STOP  •  QUIT  •  CANCEL  •  UNSUBSCRIBE  •  END

After opting out, you will receive one final confirmation message and no further messages will be sent from that number. Opt-out takes effect immediately and is permanent until you choose to re-subscribe.

If you have previously opted out and would like to receive messages again, reply START or YESto the business's number.

You may also re-enroll by calling the business again and providing verbal consent through the AI agent as described in Section 2.
